How to initially charge the lead-acid battery?

The initial charge of the lead-acid battery The new initial-use battery must be initially charged (Initialcharge) before it is put into normal use. The initial charging usually adopts the segmented constant current charging method, that is, the first stage uses a larger charging current to charge, generally about 1/10 of the battery capacity; the second stage uses a smaller charging current to charge, generally the first stage of charging current half. Taking a battery with a capacity of 200 ampere hours (A/H) as an example, the charging current in the first stage can be 15-20 amperes; the charging current in the second stage can be 7-10 amperes. If the ambient temperature is high or the electrolyte is overheated, the charging current can be reduced or even temporarily stopped. The charging time of the first stage is generally about 24 hours, and the second stage is generally shorter than the first stage. The specific time is adjusted according to the actual situation. The judgment method for the end of charging is that the battery voltage and specific gravity reach the normal value, uniform bubbles appear on the upper and lower plates, the electrolyte is clear, the specific gravity remains stable for a long time, and a large number of bubbles appear when recharging after stopping the charging for a period of time. The device that converts chemical energy into electrical energy is called a chemical battery, generally referred to as a battery for short. After discharging, the internal active material can be regenerated by charging to store electrical energy as chemical energy; when it is to be discharged, chemical energy is converted into electrical energy again. This type of battery is called a storage battery (StorageBattery), also called a secondary battery. The so-called battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary. Storage Battery (Storage Battery) is a device that directly converts chemical energy into electrical energy. It is a battery designed for rechargeability. It is recharged through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery. Belongs to secondary battery. Its working principle: When charging, use external electric energy to regenerate internal active materials, store electric energy as chemical energy, and then convert chemical energy into electric energy output when discharging, such as cell phone batteries commonly used in life. It uses a lead-based grid filled with spongy lead (also called a grid) as the negative electrode, and a lead-based grid filled with lead dioxide as the positive electrode, and uses dilute sulfuric acid with a density of 1.26--1.33g/mlg/ml as the electrolyte. When the battery is discharging, metallic lead is the negative electrode and an oxidation reaction occurs to produce lead sulfate; the lead dioxide is the positive electrode and a reduction reaction occurs to produce lead sulfate. When the battery is charged with direct current, elemental lead and lead dioxide are respectively generated at the two poles. After removing the power source, it returns to the state before discharge, forming a chemical battery. The battery can be charged and discharged repeatedly. Its cell voltage is 2V. The battery is a battery pack composed of one or more cells, referred to as storage battery, the most common is 6V, and there are 2V, 4V, 8V, 24V storage batteries. For example, the battery used in the car (commonly known as the battery) is a 12V battery pack with 6 batteries connected in series.
